Risk Assesment of Lahar Flow Hazard in Merapi Volcano

Merapi Volcano in Sleman, D.I.Yogyakarta. The height of Merapi Volcano around 2,968 meters above sea level and has experienced 84 times (event) until 2010 within eruption average is 5 years. Due to the active crater of Merapi volcano is now open to the west - southwest. So that during the growth of the lava still in dome and not go beyond the walls of the crater, the eruption will be heading west - south-west. The method in lahar flow assessing to settlement used qualitative methode include with aprroch is spatial approach, ecological approach and disaster approach with the technique of spatial multi-criteria analysis. Result analysis from this research namely (a) potential hazards, (b) vulnerability, (c) element at risk, (d) capacity, (e) risk assesment. We also given recommendation for mitigation in that area.
